Objective. To evaluate the possible risk of dealing with an unsuspecte
d primary carcinoma of the fallopian tube during laparoscopic surgery.
Methods. We performed a countrywide sun ey in Austria concerning lapa
roscopic procedures in cases of primary carcinoma of the tube. The que
stionnaire consisted of questions regarding the pre-, intra-, and post
operative management. Results. Of 18,435 laparoscopies in cases of an
adnexal mass, 5 cases were reported, when laparoscopy was performed on
an unsuspected carcinoma of the tube. Therefore, the risk of detectin
g this malignancy during laparoscopy after preoperative evaluation is
1 in 3687 cases (0.028%). Conclusion. The risk of encountering an unsu
spected primary carcinoma of the fallopian tube during laparoscopy in
Austria is an extremely rare situation. In case of a malignancy, a sta
ging or debulking laparotomy should be performed immediately or as soo
n as possible. (C) 1998 Academic Press.
